Equivalent & Substitute Parts for D0816-01

Part Overview

The D0816-01 is a 16-position DIP socket manufactured by Harwin Inc., designed for through-hole mounting applications requiring gold-plated mating contacts and wire wrap termination. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The socket accommodates 16-pin DIP packages with 0.3" row spacing and 0.100" pitch, suitable for IC and transistor applications across industrial and commercial temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D0816-01 is determined by strict equivalence across the following critical parameters:

• Position Count & Configuration: 16 positions in 2 x 8 arrangement
• Pitch Specifications: 0.100" (2.54mm) mating and post pitch; 0.3" (7.62mm) row spacing
• Contact System: Gold-plated beryllium copper mating contacts; tin-plated brass posts
• Mounting & Termination: Through-hole mounting with wire wrap termination
• Electrical Performance: 1 A current rating; 10mOhm contact resistance
• Environmental Compliance: UL94 V-0 flammability rating; -55°C to 125°C operating range

The identified substitutes—D0816-42 (Harwin Inc.) and 123-87-316-41-001101 (Preci-Dip)—meet all critical electrical and mechanical parameters. Both are active products with current manufacturing status and enhanced RoHS3 compliance, addressing the obsolescence of the original D0816-01.

Parameter Comparison

Engineering Selection Recommendations

D0816-42 (Harwin Inc.) is the primary substitute for D0816-01. Both components share identical electrical and mechanical specifications, with D0816-42 offering active product status and ROHS3 compliance. The transition from the obsolete D0816-01 to D0816-42 requires no design modifications. Packaging differs (bulk versus unspecified original), which may affect procurement and handling procedures but does not impact functional performance.

123-87-316-41-001101 (Preci-Dip) provides an alternative from a different manufacturer while maintaining full electrical and mechanical compatibility. This part is also active and ROHS3 compliant. The mating contact finish is specified as flash gold rather than 10.0µin thickness; this represents a minor specification variation that does not affect functional equivalence for standard DIP socket applications. Packaging is supplied in tube format.

Both substitutes address the obsolescence of D0816-01 and provide improved regulatory compliance through ROHS3 certification. Selection between D0816-42 and 123-87-316-41-001101 should be based on procurement availability, packaging requirements, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can D0816-42 be used as a direct replacement for D0816-01 without PCB modifications?

A: Yes. D0816-42 maintains identical pitch, position count, row spacing, mounting type, and termination specifications. No PCB layout changes are required.

Q: What is the difference between the mating contact finish specifications in D0816-01 and 123-87-316-41-001101?

A: D0816-01 specifies 10.0µin (0.25µm) gold plating thickness on mating contacts, while 123-87-316-41-001101 specifies flash gold. Both provide gold-plated beryllium copper contacts suitable for DIP socket applications. Flash plating is a thinner, cost-effective alternative that maintains electrical performance for standard IC insertion cycles.

Q: Are there packaging differences between the substitute parts?

A: Yes. D0816-42 is supplied in bulk packaging, while 123-87-316-41-001101 is supplied in tube packaging. The original D0816-01 packaging specification was not provided. Packaging selection affects handling, storage, and procurement logistics but does not impact electrical or mechanical performance.

Q: Why is RoHS compliance important for this substitution?

A: D0816-01 is RoHS non-compliant, while both D0816-42 and 123-87-316-41-001101 are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the compliant substitutes ensure regulatory alignment and reduce supply chain risk.

Q: Are the operating temperature ranges identical across all three parts?

A: Yes. All three parts operate across -55°C to 125°C, ensuring thermal performance equivalence for industrial and commercial applications.

Q: Can these sockets be used interchangeably in existing designs?

A: D0816-42 and 123-87-316-41-001101 are electrically and mechanically equivalent to D0816-01. Interchangeability is confirmed across all critical parameters: position count, pitch, contact materials, current rating, and contact resistance. Substitution is valid for direct replacement applications.
